DOOR-CHECK.

SPECIFICATION forming part of Letters Patent NO. 373,774. dated November 22, 1887,

Application tiled October 24, 1885. Serial No. 180,858.

To all whom it may concern..-

Be it known that we, GEORGE A. HOWARD, WILLIAMH. HULL, and CHARLES S. BLACK, citizens of the United States, residing at Buchanan, in the county of Berrien and State of Michigan, haveinvented certain new and useful Improvements in Door- Checks; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart ofthis specification.

Figure 1 of the drawings isa representation of this invention, and is a vertical section taken where line a: 00 is marked "on Fig. 2. Fig. 2 is a front view.

Our invention relates to door-checks; and it consists in the construction and novel combination of parts, as will be hereinafter fully described, and pointed out in the claim.

Referring by letter to the accompanying drawings, A designates the door, to the inner face of which, near its bottom, the improved door check and fastener is secured.

B designates an annular plate of metalsuch as malleable iron, or any other metal, material, or compound which is sufficiently durable and suitable for the purpose. On its front face the plate B is provided with a central raised boss, O, the latter being provided with a central screw-hole, D, for the passage of the securing-screw E. The edge of the annular plate B is provided with an integral flange, F, inclined outwardly from the center ofthe plate, as shown in Fig. 1, and having upon ita stoplug, G, situated at a suitable point above the center of the plate. On its rear face the plate B is provided with three pointed. spurs, H, which enter the face of the door when the plate B is in place, and prevent the plate B from turning on the screw E.

I designates the check lever, which coinprises the lever-arm I and the integral sector- At its inner end the lever arm I is provided with an eye, K, which rests against the face of the central boss, 0, and turns upon the securing-screw E when the check-lever I is operated.

The curved binding-bar I of the sectorframe .1 is eccentric to the screw E, so that the lever I has to be turned a less distance to (No model.)

This device serves as a check to hold the door open at any angle or place required, and also as a lock to secure the door when closed. It may also be used as a fastener for windowblinds and other devices, where applicable.

It is always attached and ready for use, andis superior to the bolts now commonly used. It is neat in appearance, is ornamental, and prevents the door from slamming.

The shorter inner curved rib, R, of the check-lever I has its inner face beveled or inclined from the front rearwardly, so that it will engage and fit the beveled edge of the plate B, and thereby prevent twisting or straining upon the securing-screw.

The corresponding bevels of the bar R and flange F prevent the lever and sectorframe from working outwardly from the plate B and door, even should the screw E be loose, as the said bevels will direct the sector-frame inward or toward the door. The length of the bar It causes the bearing of the lever and sector-frame to be against the edge of the plate B and not on the screw E, so that said lever and frame cannot break said screw and become detached from the door.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

In a door-check, the combination, with the circular plate B, provided with the central perforated boss, 0, the securing-pointsH on its rear surface, the integral rim flange F, standing outward from the center of the plate, and the stop-lug G at a proper point on said flange, of the lever I, provided with the eccentric curved binding-bar I, the bar R, inclined to correspond and fit upon the flange F, and the finger-piece 1 all constructed and arranged substantially as and for the purpose specified.

In testimony whereof we affiX our signatures in presence of two witnesses.
